CHARLES H. PARSHALL, OF DETROIT, MICHIGAN.

IMPROVEMENT IN HAY AND COTTON PRESSES.

Specification forming part of Letters Patent No. 51,61 5, dated December19, 1865.

To all whom it may concern:

Beit known that 1, CHARLES H. PARsHALI., of the city of Detroit, countyof Wayne, and State of Michigan, have invented a new and Improved Modeot' Pressing Hay, Cotton, or any other similar substance, and I dohereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings, and lettersot' reference marked thereon, making a part of this specification.

The nature of my invention consists in applying the principle ofhydraulic pressure for the purpose ot' raising the beater B and thebed-plate D.

Figure I represents the side view of the press with the door N open,exposing to view G, the substance to be pressed. Fig. II represents theend view of the press with the doors N N open.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

I construct the frame, consisting` of four upright posts, A A, ot' therequired height, size, and strength.

The beater is of iron or other similar substance, made to tit and slideup and down between the posts.

The bed-plate D is made of any substance of suitable strength andirmness.

The rest ofthe machinery is ot' material ordinarily used for thatpurpose.

The manner of using the press is as follows: The doors N N are closedand fastened. By means of the double lever O O water is drawn from thewater-tank X into the pump L and forced through pipe P into the receiverH, forcing the piston X up, which, by means of the gearing O S, revolvesthe wheel M, lifting, by the rope and the wheel K, the beater B to thetop ofthe frame. The hay is then put into the press under the beater,and when sufficiently filled the three-way cock is turned, the waterescapes from the receiver H through the pipe Y, the piston X falls, thewheel M revolves, and the beater descends. This operation is repeatedtill suttlcient beatingis attained. The dogs or catches I I areloosened, and, falling inside, rest upon the beater, holding it in placeupon the hay. Then the three-Way cock J nnder the press is opened, andby the pump water is forced into the receiver F, which forces upward thepiston E and the bed-plate D. When the hay is thus sufficientlycompressed the doors N N are thrown open and the'bale is securely bound,the three-way cock J is opened, the water escapes, and the bedplatefalls, leaving the bale loose and ready to be removed.

To prevent undue pressure and strain on the machinery, a safety-valve,T, is attached to the pipe P, and for the purpose of keeping the gearingS in place a friction-roller, R, is placed behind and in contact withit.

I do not claim, and I hereby uuqualiedly disclaim, the originalinvention of any of the parts goin g to make up this original hay-press.

NVhat I claim as my invention, and desire to secure by Letters Patent,is-

1. Operating the beater B and elevating the platen D by means of ahydraulic press, constructed substantially as set forth.

2. In combination with the beater B and platen D, as above described,the pawls I I and doors N N, secured and constructed as and for thepurposes set forth.

3. In an apparatus for compressing hay or cotton, as described, theconstruction and arrangement of the various parts constituting thehydraulic press, as specified.
